Multi-configuration drain pan assembly

A heating, ventilation, and air conditioning (HVAC) system, comprising:

• a housing;
• a heat exchanger disposed within a section of the housing and configured to condition an air flow through the housing, the section comprising an inlet configured to receive the air flow and an outlet configured to output the air flow;
• and
• a multi-configuration drain pan assembly configured to collect condensate formed by conditioning of the air flow by the heat exchanger, wherein the multi-configuration drain pan assembly comprises:
• a first drain pan configured to selectively couple to the housing in one of a first set of positions within the housing, the first set of positions comprising a first position and a second position, wherein, in the first position, the first drain pan is disposed along a first wall of the housing such that a first side of the first drain pan is disposed at the inlet and a second side of the first drain pan is disposed at the outlet, and wherein, in the second position, the first drain pan is disposed along a second wall of the housing, opposite the first wall, such that the first side of the first drain pan is disposed at the outlet and the second side of the first drain pan is disposed at the inlet;
• and
• a second drain pan configured to selectively couple to the housing in one of a second set of positions within the housing, the second set of positions comprising a third position and a fourth position, wherein, in the third position the second drain pan is disposed about the inlet such that a third side of the second drain pan is disposed at the first side of the first drain pan, and wherein in the fourth position the second drain pan is disposed about the inlet such that a fourth side of the second drain pan, opposite the third side, is disposed at the second side of the first drain pan.
